  • Polyurethane thin-walled articles with a rough surface, and method of producing the same
    Patent number: 6143416
    Abstract: A method of forming a thin-walled article, namely a surgeon's glove, having an outer grip coating of a first elastomer on a high modulus polyurethane substrate, wherein the outer coating has a rough surface to provide surface grip and the polyurethane substrate provides the majority of the glove's thickness, the method including coating a roughened former with a first elastomer that substantially does not retain bubbles that may be formed; coating a high modulus polyurethane to the coated former to form the main body of the article; drying and/or curing the composite article; and stripping the composite article from the former, whereby the surface of the first elastomer has a rough surface to provide surface grip. A surgeon's glove including an outer grip coating of a first elastomer on a high modulus polyurethane substrate, wherein the coating has a rough surface to provide surface grip and the polyurethane layer provides the majority of the glove's thickness.
